MAPFIX (MAPFIX Ltd / Sojisoft Limited) — Indoor, room-level mobile network evidence corpus and a derived 'Delta Index' — the measured gap between what each operator's published coverage map CLAIMS at a given location and what occupant devices actually MEASURE inside the building. A passive on-device SDK records signal strength (RSRP), downlink and uplink throughput, network state, carrier identity and spatial position with no user action and under 1% battery impact; readings are validated for completeness, anomaly-flagged, then scored per operator per floor from A (claim matches reality) to F…

Indoor, room-level mobile network evidence corpus and a derived 'Delta Index' — the measured gap between what each operator's published coverage map CLAIMS at a given location and what occupant devices actually MEASURE inside the building. A passive on-device SDK records signal strength (RSRP), downlink and uplink throughput, network state, carrier identity and spatial position with no user action and under 1% battery impact; readings are validated for completeness, anomaly-flagged, then scored per operator per floor from A (claim matches reality) to F (significant shortfall). Two properties make this dataset scarce rather than merely another coverage feed. First, granularity: it is ROOM and FLOOR level, not street or H3-pixel level — indoor propagation is precisely where operator prediction models fail (the site's framing: ~95% claimed coverage versus ~62% measured indoor experience), and no coverage vendor sells room-level ground truth. Second, legal form: each output is a signed, timestamped, carrier-attributed, auditable evidence record in PDF plus machine-readable JSON, aligned to ITU-T E.812 and the BEREC crowdsourced QoS methodology, with a public methodology under academic validation — i.e. data admissible in contract negotiations, board reporting, regulatory enforcement and SLA disputes, which raw crowdsourced measurements are not. Site scope claims cover 170 countries and 500+ licensed operators, with an offline-first architecture for places connectivity tools cannot operate, plus UK Site Delta Audits (30-day passive measurement across all four UK operators, building-by-building grades with JSON export), pre-deployment all-operator on-site testing for SIM selection and DAS planning, H3-cell sub-kilometre time series, and estate-level site ranking for hotel chains, hospital trusts and university estates.

Mapfix offers (Alternative, Geospatial, Reference) — Compacted-by-design and presently small in absolute terms: every audited building yields room-by-room, floor-by-floor 30-day passive time series for all four UK operators, so per-site density is extremely high while site count is low at MVP. Scope CLAIMS (170 countries, 500+ licensed operators, an evidence map across 'every region') describe the reference frame the platform is built to cover, not an audited corpus — distinguish claimed scope from delivered depth in any commercial assessment.
Regulatory enforcement and licence-condition compliance evidence (independent verification of operator coverage claims, including the compensation trigger the site notes is otherwise worth GBP 0 to consumers); indoor coverage model training — room-level measured labels against building materials, floor and construction features are unobtainable anywhere else; SLA and contract dispute evidence for estates, landlords and enterprise buyers; DAS (distributed antenna system) and in-building solution procurement decisions and post-installation verification; multi-SIM and connectivity-failover selection for critical-operations fleets (hospital trusts, hotel chains, university estates); real-estate connectivity grading and valuation; early-warning and enforcement-prioritisation models for regulators; training claim-versus-reality discrepancy models, where the label is literally the Delta grade A-F; emerging-market coverage verification where the site notes 54 African countries have zero independent verification
Coverage spans UK, US, Other; Wireless Telecommunications, Application Software; alternative, geospatial, reference; equities.
